(adj.) Something that is tight, solid, quality, etc.
Coined by John "Cakes" Auville of the WHFS Sports Junkies. Cakes wanted a home that would not be damaged by termites. Specifically, he expressed a wish for a "
money metal house." Originally, "
money" (meaning awesome, tight, etc.) modified "metal house," (i.e., a house not made of wood), but now "
money metal" is an adjective of its own, and does not require the object it is describing to be made of metal.
